Question

1) identify which statement defines what is a gene is

a. a gene is comprised of a sequence of nucleotede which encodes a sequence of ammino acid in the protein b. a gene is the fundamental unit of hereitity, located on DNA C. a gene is located on a chromsome in the cell D. in human all diiploid cell carry the same set of genes E. all the above

2) which molecule is produced by transcription pre-mrna, Dna polymerasse, RNA polymerase, ribosome poteins

3) what happens to human pre-mrna before it leaves the nucleus a, end modificationo and splicing, b, association with ribosomal subunits, c. attachment to transport proteins.

Answer 1

1) E all the above ....all of them are genes properties

2)mature mRNA is produced from pre-mRNA from which proteins are made

DNA polymerase are the enzymes that produces DNA molecules from deoxyribonucleotides during DNA replication.During the DNA replication the template coded by RNA primase is extended by DNA polymerase forming okazaki fragments .

RNA polymerase is an enzyme which acts as the initiator for producing RNA from template DNA during transcription process.

Ribosomal protein along with rRNA makeup ribosomal subunit involved in cellular process of translation which produces proteins.

3) a...end modification and splicing
